1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

BACKGROUND/

objectivesTo study the mechanism of restoration of retinal photoreceptor ellipsoid zone (EZ), after intravitreal bevacizumab (IVB) therapy, in diabetic macular oedema (DMO). SUBJECTS/

methodsForty-four consecutive patients aged 40-65 years having type 2 diabetes mellitus (DM) with DMO were prospectively recruited for IVB therapy. It comprised of three doses (1.25 mg in 0.05 ml) of IVB at monthly intervals. Patients with other ocular and systemic diseases affecting retinal vessels and earlier ophthalmological interventions were excluded. Visual acuity (logMAR VA) was recorded. Spectral domain optical coherence tomography (SD-OCT) was performed pre and post intervention. Central sub-foveal thickness (CST) and grades of disorganization of retinal inner layers (DRIL), external limiting membrane (ELM) and EZ were assessed. Data were statistically analysed on SPSS software. Clinical trials registry: CTRI/2019/03/018135.

resultsMean logMAR VA decreased after IVB therapy from 1.78 ± 0.07 pre-intervention to 0.42 ± 0.05 post intervention (p < 0.001). Similarly, CST reduced from 354.23 ± 15.0 µm pre-intervention to 233.18 ± 7.88 µm post intervention (p < 0.001). Among qualitative variables, DRIL decreased from 93.2% pre-intervention to 13.6% post intervention. Likewise, global ELM disruption reduced from 81.8 to 9.1% and global EZ disruption reduced from 79.5 to 11.4%. ELM restoration preceded EZ restoration.

conclusionAnti-VEGF therapy restores the barrier effect of ELM. It causes ELM to restore first followed by EZ restoration in DMO.
